When a cell targets a cell connected by gap junctions When a ligand-gated K+ channel opens, K+ leaves the cell. Why? A. There is more K+ outside of the cell than inside B. The outside of the cell is more negative than the inside C. There is more K+ inside the cell than outside D. K+ is pumped against its concentration gradient using the energy of ATP hydrolysis C. There is more K+ inside the cell than outside G-protein coupled receptors function? They bind extracellular ligands and trans...

BIOLOGY 1404 EXAM CHAPTER 8-11 REVIEW. CH8 - Photosynthesis CH9 - Cell communication CH10 - Cell reproduction CH11 - Meiosis and sexual reproduction CH8: PHOTOSYNTHESIS 8.1 Photosynthesis is a biological process that captures sunlight and converts it to chemical compound (carbohydrates which are stored in C-C compounds) Carbohydrates - used by organisms to power metabolism (ex. cellular respiration) Only plants, algae and cyanobacteria perform photosynthesis - called photoautotroph...
